Fig. 3.From: Interstellar grains: Effect of inclusions on extinction(a) Comparison of the observed interstellar extinction curve (Whittet, 2003) with the best-fit model curve of composite grains with graphite inclusions in the wavelength range of 3.4–0.1 00B5m. (b) Observed extinction curve in the direction of the star HD46202 and its comparison with the model curve of AR = 1.50.Back to article page
